Our plan: Smarter AI sales. Your happiness. Mischief managed.
We turn sales emails from a ‘meh’ to a resounding ‘WHOA!’ Meet our most valuable asset – the team of ever-curious AI nerds who make AiSDR an AI sales agent you can finally trust.
Why we think AI SDRs are the next big thing…
AI SDRs automate the process of booking meetings and use signal-based approaches that empower predictable conversion rates, lower acquisition costs, and greater efficiency.
Soon, AI SDRs will provide seamless AI-led demos and customer support. Leveraging a prospect’s intent, AI SDRs will help companies stand out in crowded inboxes and start conversations, allowing them to get ahead of the rest of the sales herd.
… and here’s how fast we make things happen:
H1 2023 | Idea validation
YC S23 cohort
AiSDR got into Y Combinator with just the prototype. Before any production code was written, the team signed 20 paid pilots worth more than $200k, proving real demand for an AI outbound agent.
H2 2023 | (September)
$3M seed round closed
After Demo Day, AiSDR raised a $3M seed round led by Y Combinator, Flyer One Ventures, SID Venture, and others. Revenue hit $500k ARR, customers grew to 50, and MoM growth reached 65%. The funding accelerated hiring and product development for Q4.
